Haibon told Grimaldi on the podcast that he and Iaconetti "want to make everybody happy" but also make sure that their wedding day was about them.
"I would never want to make you sad, Vanessa, obviously," he said.
"It's just sad," she said. "it's not like a birthday that happens once a year."
"It's like I vouched for you guys and I know he has too and I just, I don't want this to become about me," she continued. "I want the absolutely amazing wedding day for you guys , and if that means me watching from afar, than like, that's what it is. But I don't want this to be about me. I'm just saying like, of course I would have loved to have witnessed the love that you guys have for each other and be there to see it official, but I guess I don't need to be a part of the wedding day to see it."
Viall has not responded publicly to the podcast. Haibon and Iaconetti released a statement to E! News, saying, "None of our friends or family members have encouraged or discouraged us from inviting anyone to our wedding. We have a ton people in our life and knew that unless we had a massive wedding above our means that some people we care about unfortunately would be left out. Almost every couple getting married will feel badly about someone they had to leave off their list."
"Our invitations haven't even been created yet and therefore our guest list isn't even finalized yet," they added.
The two had starred together on seasons two and three of Bachelor in Paradise in 2015 and 2016 and announced their engagement last June, a month after going public with their relationship. He proposed while they were filming season five of the show in Mexico. They plan to wed this August in Haibon's home state of Rhode Island. In addition to being a groomsman, Tolbert is officiating the ceremony.
